1 Claim. (Cl. 29128) This invention relates to covers for ironing rolls of ironing machines, and in particular a cover in the form of a spiral with folds or darts stitched together at the ends whereby the possibility of folds or wrinkles on the ironing surface of the roll is substantially eliminated.

The purpose of this invention is to provide an ironer roll cover of one piece construction and which is so formed that substantially all lumpiness, bulging, and wrinkles are obviated.

Ironer roll covers of conventional designs derive their lumpiness and bulging, which causes wrinkles in fabrics ironed thereby, from the manner in which the ends of the cloth covers are brought together or secured against the ends of the rolls, and where the covers are held by drawstrings or fitted against the ends of the rolls it seems impossible to eliminate swelling or uneven surfaces particularly adjacent to the ends of the rolls.

With this thought in mind this invention contemplates a spiral one piece cover in which overhanging edges or flanges are fitted snugly against the ends of the ironer roll with stitched triangular-shaped darts or pleates whereby all fullness in the material of the cover is permanently eliminated.

The object of this invention is, therefore, to provide means for forming overhanging or extended edges of a one piece ironer roll cover whereby the cover nests against the outer surface and ends of the roll providing a continuously smooth ironing surface.

Another object of the invention is to provide an improved ironer roll cover which is adapted to be used on rolls of different diameters and with which heavy and light weight materials may be ironed without wrinkles.

A further object of the invention is to provide a fitted ironer roll cover that may readily be removed for washing or cleaning and that may also be readily replaced.

A still further object of the invention is to provide an improved ironer roll cover in which the ends are fitted to the roll to eliminate bulging on the surface of the roll, and in which the cover is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies an elongated sheet of cloth or other suitable material rolled to form a spiral and secured in the spiral with radially disposed rows of stitches forming triangular-shaped folds in overhanging or inturned sections at the ends of the roll providing a preformed cover, and wherein the overlapping ends of the cover are secured together with snap fasteners in the said overhanging sections.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

Figure 1 is a perspective or elevational view of the improved ironer roll cover showing the cover as it appears in use upon an ironer roll, the roll being omitted.

Figure 2 is a cross section through the ironer roll cover taken on line 22 of Figure 1, with the ends of the spiral sheet disconnected.

Figure 3 is a detail showing a section taken on line 3-3 of Figure 2, with parts broken away, and illustrating the snap fasteners in the overhanging edges or flanges, said parts being shown on an enlarged scale and partially exploded to indicate the relative positions of the parts.

.Figure 4 is an edge view of a section of one of the overhanging edges or flanges showing the method of forming the darts therein, said view being taken substantially on line 44 of Figure 1.

Referring now to the drawing wherein like reference characters denote corresponding parts the improved ironer roll cover of this invention includes an elongated sheet of material rolled to form a spiral 10 with flanges 12 at the ends and having an outer end section 14, an intermediate section 16 and an inner end section 18, and the flanges are retained in inwardly extended or fitted positions with radially disposed rows of stitches 20 thereby forming triangular-shaped darts 22.

The mean diameter of the spiral is substantially equal to the outside diameter of the ironer roll, however it will be understood that some variance is permissible as with the cover rolled on an ironer roll the diameter of the roll may be smaller or greater than that of the spiral with the cover in the free position.

As illustrated in Figure 3, a male element 24 of a fastener is spaced from the end section 14 of the cover whereby a prong 26 thereof is positioned to snap into a socket of a female fastener 28 in the flange of the intermediate section 16 of the cover. The flange of the intermediate section 16 is also provided with a male element 30 that is positioned whereby a prong 32 thereof snaps into a female socket of a fastener element 34 in the flange of the inner end section 18 of the cover.

By this means the overlapping end of the spiral cover is maintained in tension from end to end of the roll without fastening means intermediate of the ends, and although only one row of fasteners is shown and described it will be understood that any number of fastener elements may be used that may be desired, and the fastener elements may be spaced along the flanges to compensate for ironer rolls of different diameters.

By this means pre-fabricated ironer roll covers may be manufactured, shipped and stored as standard equipment, and used as desired.

The spacing and number of darts or folds in the flanges or extended edges of the cover depends upon the diameter of the roll and the use for which the cover is designed.

In the installation of the improved cover on a roll the inner end section 18 is started against the peripheral surface of the roll and the succeeding layers are rolled upon the inner layer until the complete cover is in a tight position upon the roll. The fasteners are then snapped together and the cover is secured in position without other fastening elements.

The fastening elements are readily disconnected when it is desired to remove the cover for washing or cleaning.

From the foregoing description it is thought to be obvious that a spiral ironer roll cover constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement of the several parts herein shown in carrying out my invention in practice, except as claimed.

What is claimed is:

A preformed fabric spiral ironer roll cover comprising a spiral shaped roll of fabric having inturned edges providing flanges at the ends, said cover starting from one Patented Nov. 1, 1955 7 References Cited in the file of this patent UNITED STATES PATENTS Marshall Oct. 12, 1886 Thomson July 4, 1916 Chambers Sept. 23, 1924 Trench May 19, 1925 Parsons Jan. 11, 1938 FOREIGN PATENTS Great Britain Jan. 16, 1930
